To all whom it may concern:

Be it known that 1, CHARLES L. DEPOL- LIER, a citizen of the United States, and residing in the borough of Brooklyn of the city of New York county of Kings, in the State of New York, have invented certain new and useful Improvements in Take-Up Devices for l/Vrist-Straps for Watches, of which the following is a specification, reference being had to the accompanying drawing, forming apart hereof.

Straps, whether of leather or fabric, for wrist-watches are sometimes made each in two partswhich are attached respectively to eyes or bows of the watch or watch-carrier adapted to be connected at their free ends by an ordinary buckle. When the two parts of such a strap are disconnected it frequently happens that the watch falls to the ground because the wearer must manipulate the buckle with the fingers by one hand. Another form of strap, which is free from the objection just referred to, is the 011epiece strap which is connected to the watch at one end through an eye or bow and at the other end is passed through another eye or how and is provided with some sort of a fastening device by which the free end can be secured to the standing part of the strap at any desired point for the purpose of adjusting the strap to the wrist of the wearer. This invention relates to the clips or fastening devices by which the free ends of such straps are secured in desired position to the standing parts of the straps and it has for its object to provide a simple and inexpensive clip of this character which can be readily loosened from the standing part of the strap and can be as readily engaged therewith by the fingers of one hand. The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated and in which,

Figure 1 is a perspective view of a watch and a wrist-strap equipped. with the improved clip.

Figs. 2 and 3 are respectively a face yiew and an end view of the clip shown in Fig. 1.

Figs. 4 and 5 are respectively a face view and an edge view showing a slight modification.

Figs. 6 and 7 are face views showing other modifications.

The watch-case a is shown in Fig. l as provided at diametrically opposite points with eyes 6 and 0 which may be of the disappearing type and adapted for engagement with connecting devices d and 6. One end of the strap f, of leather or suitable fabric, is connected directly to the connecting device (Z. The other end of the strap is passed through the connecting device 6 and is then secured to the improved clip 9 which may be slipped in one direction or another upon the standing part of the strap 6 to take up more or less of the strap and so permit the strap to be ad usted to the wrist of the wearer. The clip 9 consists essentially of a flat plate of metal having two slots 9 and 9 through which the standing part of the strap passes, under the middle bar and over the outer bars 9* and The free end of the strap 7 is formed with a loop f which engages the outer bar 9*. The friction between the clip and the strap, by reason of the deflection of the strap over the middle bar of the clip is sufficient to prevent movement of the clip upon the standing part of the strap under the influence of a pull exerted on the clip, especially when the space between the middle bar 9 and the bar g is restricted by the engagement of the looped end of the strap with the bar 9 and in order to permit the clip to be moved readily upon the standing part of the strap by grasping it endwise between the fingers of one hand it is necessary to relieve the pressure on the strap either by slipping the clip from the standing part of the strap or from slipping the looped end of the strap readily from the bar 9 and for less readily effecting a partial disengagement of the clip from the standing part of the strap if desired. In Fig. 6 is shown a construction which more readily permits the disengagement of the clip from the standing part of the strap and in Fig. 7 is shown another construction which permits the easy disengagement of the clip from the standing part of the strap. As shown in Figs. 2 and 3 the bar 9 is rigidly connected with the bar 5/ at one end and is free therefrom at the other end, the gap being closed by a latch pivoted upon the end of the bar 9 and having a hole for frictional engagement with a stud g on the main part of the clip. The construction shown in Figs. 4 and 5 is similar to that shown in Figs. 3 and 4 except that the latch 9 which bridges the gap, is a spring-pressed sliding latch.

In the construction shown in Fig. 6 the bar g is provided with a pivoted latch 9 as in the construction shown in Figs. 3 and 4E and the bar 9 is also provided with a spring-pressed sliding latch 9 to bridge the gap between it and the main part of the clip. lVith this construction it is easily possible to disengage the clip from the standing part of the strap, even without disengaging the looped end from the bar g.

Inthe construction shown in Fig. 7 the outer bars 9 and g are pivoted upon the main part of the clip and are provided with rigid latch portions and g which engage frictionally a common stud g on the end of the middle bar 9 This construction also permits the clip to be disengaged readily from the standing part of the strap without disengaging the looped end of the strap.

Various other embodiments of the invention will readily suggest themselves.

I claim as my invention:

1. In combination with a wrist strap, connecting devices therefor including a take-up device Which consists of a flat plate having a bar and two outer bars separated from the first named bar by spaces to permit the strap to be threaded through said bars and engage the same with a frictional grip, one of the outer bars being free from the first named bar at one end and movable means to bridge the space between the free end of the outer'bar and the first named bar to permit the strap to be disengaged from the take-up devices, the wrist strap lying copies or this patent may be obtained for the outer bars being free from the first i named bar at one end and a sliding springpressed latch to bridge the space between the free end of the outer bar and the first named bar to permit the strap to be disen gaged from the take-up device.

3. In combination with a wrist strap, connecting devices therefor including a take-up device which consists of a fiat plate having a bar and two outer bars separated from the first named bar by spaces to permit the strap to be threaded through said bars and engage the same with a frictional grip, one of the outer bars being adapted to be engaged by the looped end of the strap and both of the outer bars being free from the first named bar at one end and movable means to bridge the spaces between the free ends of the outer bars and the first named bar to permit the strap to be disengaged from the take-up dev1ce.
